' 14 Claims. (Ci. 30-43) This invention relates to improvements in razors and hair clippers.

It is a purpose or this invention to provide a practicaL- 'eiilcient, economical and simple hair cutter'in which the cutting elements automati-' cally adjust themselves angularly with relation to the handle; upon which they are mounted to always present the maximum skin engaging cutting surface, irrespective of the .position the handle is held by the operator, as the device'is being moved over the surface of. the skin and around sharp curves. The invention is particularly adapted for use in power driven razors of the type used for dry shaving, that is, without the aid of lather or soap and inwhich a movable cutting element is employed. The cooperating cutting elements may be made to swing from side to side while one of the elements is in motion for the cutting operation. Therefore, it is a further 2 purpose of this invention to provide means to bring about this simultaneous, dual motion.

A further purpose of this invention is to improve the hair cutting efliciency of a power driven hair clipper or razor.

25 A further purpose of this invention resides in drawing, constituting a feature of this disclosure,

as and in which:

Fig. 1 is a side elevational view of a cutter unit for power razors embodying the invention.

Flg. 2 is-a top plan view thereof. Fig. 3 is a sectional'view taken along line 3-3 40 of Fig. 1.

Fig. 4 is a view similar to Fig. 3, but showing the cutter unit in an angular position.

Fig. 5 is a perspective detailedview of a section of cutter unit or head embodying the invention. 45 Fig. 6 is a perspective partial view of inner cutter element, showing the slots in angular relation.

Fig. 7 is a perspective view of the top part of a power razor embodying and employing the inven- 50 tion.

Fig. 8 is a sectional view of a power razor head in a modified form.

The drawing shows some examples of power razors incorporating the invention and by which 55 the same may be'realized. Referring to Figs. 1-7,

inclusive, let the numeral 23 represent the hollow head carrying a skin-ensa ihz shear-plate, which head may be rectangular in shape, having in the shear plate thereof the plurality of alternately disposed blades and slots, 25a, 2311, respectively, 5 the blades 23 being here shown as having tapered end projections 25c for guiding the hair into the slots 25b for the cutting operation. The hollow head 23 is fixedly secured to the depending end members 26, 21, which are pivotally or swingably 10 attached to the ends or arms of the substantially U-shapedbase member 30, as by means of the pintles 23, 23, respectively.

The reciprocable hollow cutter member 3| which is made to operate within the hollow head 1 or element 25 is provided with slots which may be straight across, as shown at-25b in Figs. 1 and 5, or angularly disposed with relation to the cutter as indicated by the numeral 3") in Fig. 6. The

side wallspf cutter 3| are provided with downwardly-disposed extensions 34, 35 having the preferably centrally located recesses or slots 38 within which partially projects the transverse preferably arcuate central extension 43 of slide 31. Cutter 3 I, is retained in the skin-engaging shear-plate head 25 with its cutting edges in engagement with groove or channel which slidingly receives the longitudinal projection or rail 50a of slide 31.

Slideway 50 ismade part of or is secured to the base or support 30. Slide 31, slideway 50 and base 30 have registering openings 38, 38a, 38b, respectively, to. receive the conventional motordriven shaft and eccentric pin (not shown) for engagement with the slide 31, to reciprocate the latter for thehair-cutting operation.

The cutter 3|. is preferably provided with the side recesses or cut-outs 33 adjacent the tapered 45 end projections 25c of the top shearing plate, the purpose of said cut-outs 33 being to prevent any binding of the cutter thereby assuring easy movement of the cutter with relation to the shear plate; and also to provide clearances for hairs, particularly long ones to" straighten out prior to the cutting operation.

The cutter head may be provided with longitudinally-disposed side 'guards, an example of which are the rollers 40, 4| mounted on shafts The side guards prevent the blade projections 25c from irritating the skin during the cutting of the hairs.

The openings 00a and 30b in the parts 80 and 30 are made larger longitudinally of the base 50 than the opening 38, but of the same lateral extent to permit ofthe lateral movement of the eccentric pin to reciprocate the cutter member II.

It will be observed that'both the skin-engaging shear-plate and cutter in engagement therewith are pivotally mounted to swing together with relation to the base 30, and since the latter is adapted to be immovably mounted on handle H (see Fig. 7) which may house the motor operating the eccentric pin, the said plate and cutter are free to be swung with relation to the handle H. It will be further observed that regardless of the angular position assumed by the cutting elements,

slide 31 at extension 43, will always engage the cutter member II in slot 36 to reciprocate the cutter.

During the shaving or hair-cutting operation, the cutting elements automatically take their proper angular hair clipping position independent of the position of thehandie and frame upon which they are pivotally mounted, and as the shaving operation progresses, the cutting elements will pivot from side to side, their swing-' ing movement in either direction being limited by the top of arcuate projection or extension 43, which is so proportioned with respect to the depth of the slot 36 that the bottom of the latter engages a side of the-projection before swinging past the center thereof, therebyserving as a stop for the swinging motion of the head in both directions. The relative angular position between the handle and the surface of the skin may remain unchanged and as the shear-plate is passed over the skin it will remain flat thereagainst going around the curves of the applied skin surface and pivoting or swinging when necessary.

In Fig. 8, part I03 corresponds to base 30; I01 to slideway 50; I09, I0Ia and I00a to openings 38!), 38a and 30, respectively of Figs. 3 and 4. Part I06 corresponds to slide 31 of Figs. 3 and 4, but in this instance slide I06 has a transverse arcuate channel or groove I05 to rockingly or swingablyreceivethecutter I00having the laterally extending and spaced cutter parts II5 hearing upwardly against shear blades of a head IN.

The specific construction of cutter I00 and head I 0|, as shown in Fig. 8, are claimed in a divisionalapplication, Serial No. 134,536, filed April 2, 1937. The head IN is fulcrumed or pivoted by suitable means, as a pin I00, to base I03. A

spring I I6 may tensionally hold the cutter member I 00 in slidable engagement with the stationary cutter head IOI. H0 and III are the side guard members.

The cutter member I00 and slide I06 reciprocate together in slot II! with respect to the shear plate of head IOI and the slideway I01, the reciprocation being effected by a motor-driven shaft and an eccentric pin (not shown) extending within opening I06a and operating in openings I09 and N111 which are larger or wider longitudinally of the head than the former opening.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore, desire the present embodiment to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
